Nottinghamshire chased down a revised target of 140 with 15 balls to spare to beat Kent by seven wickets on the Duckworth-Lewis system.
James Taylor hit an unbeaten half-century to vindicate his decision to play in the Yorkshire Bank 40 fixture on the eve of his appearance for the England Lions against New Zealand.
It seemed as if bad weather might ruin his hopes of continuing his good start to the domestic season after Kent had managed to make 220-6 from their 40 overs.
Persistent rain during the interval delayed the Outlaws from beginning their chase; When the conditions were eventually fit for play they were given 19 overs to reach a revised target.
Twenty20 experts Michael Lumb (11) and Alex Hales (21) failed to carry on after some early boundaries but Taylor timed his knock to perfection, bringing up his 50 with a boundary through the covers that also ended the match.
Rikki Wessels was unbeaten on 37 at the other end as Nottinghamshire made it two wins from two to move to the top of Group A.
Graeme Swann had gone wicketless in Kent's innings earlier in the day, though the England off-spinner only went for 24 runs during his eight overs.
Instead it was Steven Mullaney who did the majority of the damage with the ball; he claimed 4-29 including removing the well-set duo of Rob Key (62) and Brendan Nash (41) after a second-wicket stand of 96.
The visitors lost their way for some time before Geraint Jones picked up the pace, hitting a six and five fours to race to 39. Ben Harmison, who ended up unbeaten on 33, helped add 50 runs during the four powerplay overs.
